Hi, I have gotten 4 times the BSOD in the last couple of days. It did not happen after any software nor hardware install or change. The hard disk also makes a lot of noise. This is what the WindDbg is reading on one of the minidumps (the others are basically the same): Microsoft ® Windows Debugger Version 6.6.0003.5 Copyright © Microsoft Corporation.

Caused by bad block in paging file or disk controller error. In the case when the first arguments is 0 or 1, the stack signature in the kernel stack was not found. Again, bad hardware. An I/O status of c000009c (STATUS_DEVICE_DATA_ERROR) or C000016AL (STATUS_DISK_OPERATION_FAILED) normally indicates the data could not be read from the disk due to a bad block. Upon reboot autocheck will run and attempt to map out the bad sector. If the status is C0000185 (STATUS_IO_DEVICE_ERROR) and the paging file is on a SCSI disk device, then the cabling and termination should be checked. See the knowledge base article on SCSI termination.
